1.Purpose and Significance of Stator Thermally Conductive Potting
Improve Heat Dissipation Efficiency
When a motor operates, a large amount of heat is generated. If it is not dissipated in time, the motor temperature will rise, affecting its performance and service life. Stator thermally conductive potting can quickly transfer the heat of the stator winding to the motor housing, improving heat dissipation efficiency and lowering the motor temperature.
Enhance Insulation Performance
The potting material can fill the gaps in the stator winding to build a high-quality insulating layer, enhancing motor insulation performance, preventing winding short circuits and leakage, and improving motor safety and reliability.
Protect the Stator Winding
The potting material can protect the stator winding from external environments such as dust, moisture and chemicals, and withstand vibration and impact during motor operation, preventing the winding from loosening and being damaged.
